between rowsand having for its primary object to adjustably mount the marginal cultivator teeth permitting the same to be laterally adjusted in order that the range of. cultivation may be increased or diminished, as desired.

Another object of the invention is to resiliently mount the shovel beams thereby regulating the depth of penetration of the teeth in the earth; the guide handlesvbeing in connection with'the shovel beams in order to penetrate the teeth deeper in the earth when pressure is exerted thereon.

A further object of the invention is to movably associate the shovel beamswith'the wheel frame, the latter being provided with supports with which the shovel beams are engaged at the end of the rows so as to prevent the breaking of the corn stalks or the like while the cultivator is being turned, likewise facilitating the transporation of the device from one field to another or. the like.

A still'further object of the invention is the adjustable assemblage of the various parts of the invention so that each part may be replaced when it becomes inapt for use likewise permitting the-various parts to I be disengaged for shipment or the like there-E- by occupying a minimum amount ofspace. Other objects as well as the nature, char-" acteristic features and scope of my inven-if tion will be more readily understood from the. following descriptlon taken in connec-i'; t1on with the accompanying drawings and? Specification of Letters Patent.

plan view of the same; Fig. 3 isa cross sectional view taken on the line 33 of Fig. '2 showing the manner in which one of the shovel beams is supported on one side of the Wheel frame when the cultivator teeth are to be disengaged from the earth; Fig. iris a cross sectional view taken on the line of F ig. 2 and looking in the direction ofthe' arrows, showing to advantagethe'manner n which the draft hook is associated with the wheel frame and the shovel beam con necting plates; and Fig. 5 is a sectional view taken on the line 55 of Fig. 2 and looking in the direction ofthe arrows showing the manner in which the shovel beam is resiliently carried by the wheel frame.

In the drawings wherein is illustrated the preferred embodiment of this invention a wheel frame 6 is provided which in the present instance comprises a pair of sections 7 and 8 the forward end of each of which is offset and have the inner longitudinal edges thereof snugly engaged, the free terminals thereof provided with elongated longitudinally extending slots which are engaged with the squared shank of the draft, hook 9, said draft hook being held in engagement therewith through the medium of a nut and bolt 10. The offset forward ends of the sections 7and 8 are provided with cut out portions on the upper and lower faces thereof in which are mounted plates 11 the opposite end of each of which is provided with an aperture 12 throughwhich is mounted a bolt 13, said plates being secured in said sections 7 and 8 by bolts 14: as shown to advantage in Fig. 4:, the plates lying flush with the upper and lower faces of the sections 7 and 8 by the provision of the cut out portion in the latter." The rear end of the sections 7 and 8 arelikewise detachably connected and have mounted therebetween a spacing block 15. Revolubly mounted between the sections and 8 is a traction wheel 16 which is of pointed out in the claims forming a partofi the i y configuration n h the axle this specification; 1 V

Referring to the drawings F1gur'e 11s a side elevation of acultivator constructed in accordance with my invention showing 1' thereof mounted on theupper face of the sections 7 and Sand secured theretoby looped straps 17, said wheel being provided in order to facilitate the actuation of the cultivator likewise enabling the device to be more readily guided by the operator and permitting of the resiliently mounting of the shovel beams which will be presently described.

A pairof shovel beams 18 are provided each of which extends in parallelism with the sections 7 and 8 and has the rear end thereof arcuated in the usual manner and a shovel or tooth 19 detachably associated with the end thereof, the forward end of each of said beams having an eye bolt '20 extending therefrom which engages with one of the bolts 13 thereby permitting vertical movement of the shovel beams for a purpose which will subsequently appear. Each of the shovel beams has hingedly connected thereon an auxiliary shovel beam 21 which is identical in configuration to the shovel beams 18 with the exception that the auxiliary beams have the forward extremities thereofhingedly connected to ears 22, of the shovel beams 18 thereby permitting lateral. movement ofthe auxiliary beams 21 in order to variate the range of cultivation according to the space of earth desired to be cultivated between the rows.

In order to retain the auxiliary beams 21 in a predetermined position a screw threaded shank 23 is pivotally mounted on each of the beams 17 having'a vertical axis 24 so as to allow the bolt to move longitudinally with respectto the beams 18, eachof said boltsextending throughslots 25 in the auxiliary beams 21 and being held from movement thereon by jam nuts 26.

. In order to-yieldingly engage the teeth 19 of the shovel beams 18 and 21 with the earth a suitable resilient means is provided and 80f the wheel frame 6. It is therefore seen that the teeth19 will be permitted to normally very slightly penetrate the soil but may be deeply penetrated the'reinsh'ould it be so desired, by the pressure which is exerted on the guide handles 31', said handles being secured in the ordmary manner to the shovel beams 18, and serving the dual purposeof facilitating the guiding .of

the cultivator and at the same time regulatingto a certain extent the depth of'penetr'zition of the cultivator teeth.

,It is well known in this art that very often it is desired to disengage the cultivator teeth from the earthat the endsxo'f rows when turning the cultivator in order toprev'ent the breaking of thecorn-stalks or the like between; which the cultivator zoperously pointed. out.

ates, since space at the ends of the rows is very often limited in permitting of the passing of the cultivator to a suflicient dist'anee'beyondtlieends of tlije rows to "insure the teenager the same without breaking down'of the corn stalks or the like as previ In order to eliminate this I have detachably arranged on the shovel beams 18 suitable hook members 32 which are engaged by eye bolts 33 of1the wheel frame sections 7 and 8 whenit is desired. to retain the shovel beams out ofengagement with the earth, the vertical movement of the shovel beams be ng .piermittedginyiew of the manner infwhichfthe eye bolts 20 at the forward ends thereof are mounted on the bolts 13.

v In operation we will assume that the cul-x tivajtor teeth 19, are in engagement with the earth inwhich instance only, a slight penetration is provided for by the elasticgelements 27. Should itcbe desired to penetrate the teeth deeper the earthpressu-re is; i

exerted on the handles 31 by the operator until "the. desired depth of penetration has been reached. lVh en; it is desired to disengage the teeth from theearth as=atthe ends ofrows'or the like as previously pointed out, pressure is exerted onthe lower side of r the handles 31 causingthe teeth to be raised fromengagementwith the earth and pen mittingfthe eye bolts 33 to be engaged with the ihooks by the lateral movement of the beams 18 as is obvious. movement of the auxiliary beamsill is of course permitted in View of the threaded shank It will be understood that the above description and accompanying drawings; comprehend only the general and'preferrecl em-V bodlment of my invention and that various minor changes in. details of constructiom. proportion and arrangement of Ethe parts may be made within the scope of the appended claims and without sacrificing any.
